AUTOLOAD is very slick. You can program anything you want to have 
happen if an undefined sub/method is called. Like if you had 10 
header_xxx sub/methods that were almost all exactly the same, you could 
use AUTOLOAD to call a single, central sub/method, passing in an 
argument for the tweak (instead of having to explicitly declare 10 
sub/methods)... See "perldoc perltoot".

Looks like this would work for you too?

   &{"header_$who"} if (defined &{"header_$who"});

My test:

[jhannah-mac:~] jhannah% cat j.pl
#!/usr/bin/perl

my @subs = qw( one two three );

foreach (@subs) {
   &$_ if (defined &$_);
}
sub one { print "1\n"; }
sub three { print "3\n"; }

[jhannah-mac:~] jhannah% ./j.pl

HTH,
